Definitions
- the invention relates generally to anti-cancer compounds and more specifically to glucose conjugates of triptolide and analogs thereof, and methods of treating cancer using such compounds.
- Triptolide is an active component from the traditional Chinese medicinal plant Thunder God Vine. It has been shown to possess anti-inflammatory, immunosuppressive and anticancer activities, among others. Its molecular target has been identified as the XPB (ERCC3) subunit of the general transcription factor TFIIH. It works by blocking RNAPII transcription initiation and nucleoside excision repair. Triptolide and analogs have been developed as new anticancer and immunosuppressive drugs. Unfortunately, dose-limiting toxicity and insolubility have been major hurdles for its development as a new drug.
- the present invention is based on the seminal discovery that conjugation of triptolide with glucose to form glucose-triptolide conjugates provides compounds with effective anti-proliferative activity and improved tolerability as compared to naturally occurring triptolide compounds.
- the invention provides an anti-proliferative effective amount of a glucose-triptolide conjugate compound for use in the treatment of cancer.
- glucose-triptolide conjugate compounds have the structure of Formula I: T&A-L 1 -Sugar (I)
- the cancer may be one of the following, but not limited to bladder cancer, breast cancer, ovarian cancer, pancreatic cancer, and gastric cancer, cervical cancer, colon cancer, endometrial cancer, head and neck cancer, lung cancer, melanoma, multiple myeloma, leukemia, non-hodgkin's lymphoma, prostate cancer, rectal cancer, malignant melanomas, alimentary/gastrointestinal tract cancer, liver cancer, skin cancer, lymphoma, kidney cancer, muscle cancer, bone cancer, brain cancer, eye or ocular cancer, rectal cancer, colon cancer, cervical cancer, bladder cancer, oral cancer, benign and malignant tumors, stomach cancer, corpus uteri, testicular cancer, renal cancer, throat cancer, acute lymphocytic leukemia, acute myelogenous leukemia, Ewing's Sarcoma, Kaposi's Sarcoma, basal cell carcinoma and squamous cell carcinoma, small cell lung cancer, choriocarcinoma, rhabdomyosarcoma,
- the cancer is prostate cancer.
- the cancer is metastatic cancer.
- T&A moiety is compound 1 and the sugar is compound 19 , 20 , 37 or 38 .
- L 1 is a direct bond, -COCH 2 CH 2 CO-, or -CH 2 -.
- T&A moiety is compound 1 and the sugar is compound 19 .
- glucose triptolide conjugate compound has a Formula G1-9.
- the compound is Formula G4.
- Formula G1-9 are illustrated in the structures provided herein.
- the invention also provides a pharmaceutical composition comprising the compounds listed above.
- the method of treatment includes administration intravenously, such as at a dosage of about 0.1 mg/kg to 2 mg/kg per dosage.
- the compound is administered once daily for up to about 4 weeks.
- the method may further include administering a chemotherapeutic compound, for example, prior to, simultaneously with, or following administration of a compound of the invention.
- the method of synthesizing a glucose-triptolide conjugate compound includes synthetic scheme II or III. These schemes are provided herein.
- an anti-proliferative effective amount of a glucose-triptolide conjugate compound is administered to a subject in a method to treat possible organ rejection in subjects that have undergone an organ transplant.
- an anti-proliferative effective amount of a glucose-triptolide conjugate compound is administered to a subject in a method to treat autoimmune diseases.
- immune related diseases include but are not limited to: Acute disseminated encephalomyelitis (ADEM), Addison's disease, Ankylosing spondylitis, Antiphospholipid antibody syndrome, Autoimmune hemolytic anemia, Autoimmune hepatitis, Autoimmune inner ear disease, Autoimmune Lymphoproliferative Syndrome (ALPS), Autoimmune polyendocrine/polyglandular syndrome, Autoimmune thrombocytoipenia purpura, Balo disease, Behcet disease, Bullous pemphigoid, Cardiomyopathy, Celiac sprue-dermatitis herpetiformis, Chronic fatigue immune dysfunction syndrome (CFIDS), Chronic inflammatory demyelinating neuropathy, Cicatrical pemphigoid, Coeliac disease, Cold agglutinin disease, CREST syndrome, Crohn's disease, Cystic fibrosis, Degos disease, Dermatomyositis, Diabetes (Type I or Ju
- a library of glucose conjugates of triptolide and analogs thereof is used to screen for compounds for treating cancer.
- a library of glucose conjugates of triptolide and analogs thereof is used to screen for compounds for treating possible organ rejection.
- a library of glucose conjugates of triptolide and analogs thereof is used to screen for compounds for treating autoimmune disease.
- the present invention is based on trying to solve the issues of solubility and toxicity associated with triptolide. It was hypothesized that if triptolide could be conjugated to glucose, the two aforementioned problems associated with triptolide could be addressed.
- the glucose-triptolide conjugates would be preferentially taken up by cancer cells and they should also exhibit much higher water solubility due to the water solubility of glucose moiety.
- cancer or "cancerous growth” means the uncontrolled, abnormal growth of cells and includes within its scope all the well-known diseases that are caused by the uncontrolled and abnormal growth of cells.
- Non-limiting examples of common cancers include bladder cancer, breast cancer, ovarian cancer, pancreatic cancer, and gastric cancer, cervical cancer, colon cancer, endometrial cancer, head and neck cancer, lung cancer, melanoma, multiple myeloma, leukemia (e.g. myeloid, lymphocytic, myelocytic and lymphoblastic leukemias), non-hodgkin's lymphoma, prostate cancer, rectal cancer, and malignant melanomas.
- leukemia e.g. myeloid, lymphocytic, myelocytic and lymphoblastic leukemias
- non-hodgkin's lymphoma prostate cancer, rectal cancer, and malignant melanomas.
- chemotherapeutic agents can be used prior to, simultaneously with or following treatment with invention compounds.
- Illustrative agents include but are not limited to, taxol, cytochalasin B, gramicidin D, ethidium bromide, emetine, mitomycin, etoposide, tenoposide, vincristine, vinblastine, colchicin, doxorubicin, daunorubicin, dihydroxy anthracin dione, mitoxantrone, mithramycin, actinomycin D, 1-dehydrotestosterone, glucocorticoids, procaine, tetracaine, lidocaine, propranolol, and puromycin and analogs or homologs thereof.
- Therapeutic antibodies or other proteins are also envisioned in combination therapies of the invention.
- This example illustrates the synthesis of glucose-conjugated triptolide compounds.
- Five glucose conjugates with different types of linkers connecting glucose to triptolide were synthesized, designated G1--G5 (schemes I-III).
- the Octanol-water partition coefficient, LogP were significantly improved over triptolide itself ( Fig. 1 ).
- the activity of the different glucose-triptolide conjugates was assessed in vitro ( Fig. 2 ). It was found that they differ in their anti-proliferative activity as measured by tritiated thymidine incorporation with G4 and G3 showing moderate activity, while G1, G2 and G5 exhibiting significantly reduced activity. The ability of the glucose conjugates to inhibit the ATPase activity of XPB in the TFIIH complex was also addressed. Interestingly, none of the five glucose conjugates showed appreciable inhibitory activity, suggesting that the cellular activity was a result of breakdown of the conjugates either in cell culture or upon entry into cells.
- the in vivo antitumor activity of the glucose-triptolide conjugate G4 was determined using an established metastatic prostate cancer model (Reference 1).
- the luciferase---expressing prostate cancer line PC3/ML was injected into NOD/SCID/IL2r ⁇ null (NSG) mice through the tail vein.
- NSG NOD/SCID/IL2r ⁇ null mice
- the metastasis of the injected prostate cancer cells into liver, kidney, lung and bone can be monitored in live animals by bioluminescent imaging (BLI). It was shown that this is a reliable model with reproducible liver metastasis and all animals succumb by Week 7 after injection of cells (or Week 4 after initiation of treatments).
- mice treated with 11 had lower tumor burden during Weeks 1 and 2 compared with those treated with triptolide.
- both treatment groups showed undetectable tumor cells while all animals in the untreated groups died.
- tumors immediately returned in animals treated with triptolide. But no tumor cells were detectable in those treated with G4 till the end of the experiment, revealing sustained anticancer activity of G4 in vivo.
